The service manual is as described and received the link to the download sooner than expected. Great service, quality product. This site is a big help in the electronics repair business.
I ordered this manual sometime in the afternoon and I received it on my e-mail the same evening.
This is a fantastically good and properly scanned copy of the original manual. All pages are of the same scale and they overlap each other. It means that you can print the manual and easily make it as a convenient paper manual.
The content of the manual is fantastic. Alignment descriptions, PCB layouts and elementary diagrams are explicit and precise. I immediately found what I was looking for. Thanks to this manual and Owner-Manuals.com my amplifier is alive again. Many thanx indded!
